The statistical analysis of water source ,wastewater sorts ,wastewater quantity and water consumption in a coal-fired power plant was done ,and the system strategy to achieve zero wastewater discharge was proposed .Taking Heyuan power plant as an example ,a typical zero wastewater dis-charge system for coal-fired power plant was established .The operation technology of a recycle cooling system with a high concentration ratio of 10 times more was developed ,and the treatment process for high concentration end wastewater was developed in which two levels of pretreatment are combined with evaporation and crystallization , thus achieving the comprehensive utilization of wastewater sludge and crystallization salt successfully without secondary pollution .The study is valuable for the development and application of zero wastewater discharge system of coal-fired power plant , wastewater treatment ,water resource utility ,comprehensive utilization of solid waste and so on .
